A plot might involve a magic - induced situation where a spell goes wrong and creates a baby that has a connection to both Lucy and Laxus. They then have to figure out how to deal with this unexpected addition to their lives. Along the way, they learn about each other's pasts and secrets, which brings them closer together as they raise the baby.
One possible plot could be that Lucy and Laxus accidentally end up having to take care of a baby together. Maybe they find a lost baby during one of their guild missions. At first, they're both really clumsy and unsure of how to handle it. But as time goes on, they start to develop a bond not only with the baby but also with each other in a new, more family - like way.
Perhaps in the fanfiction, Lucy discovers she's pregnant with Laxus' baby. This causes a stir in the guild. Laxus is initially shocked but then becomes determined to be a good father. They face many challenges, like dealing with the reactions of their friends and family in the guild, as well as preparing for the baby's arrival. Lucy also has to balance her pregnancy with her guild duties, and Laxus is there to support her every step of the way.
One possible plot could be that they accidentally end up having to take care of a baby during a mission. Maybe they find an orphaned baby in a dangerous situation and decide to protect it. This could lead to some really cute and funny moments as they struggle to take care of the baby's needs while also dealing with the threats around them.
The antagonists could be dark guild members. They might hear about the special baby that Lucy and Laxus are involved with. Maybe the baby has some sort of powerful magic within it, and the dark guild wants to steal the baby for their own evil purposes. So they constantly try to attack Lucy and Laxus to get their hands on the baby.
Well, perhaps Laxus has some misguided notion that Lucy has information vital to the guild's safety. So he kidnaps her thinking he can extract it from her quickly. But in reality, Lucy has no such information and she has to convince Laxus of that.
One idea could be that they discover the pregnancy unexpectedly. Maybe they were in the middle of a big adventure in their magical world and then Lucy starts showing signs. It throws them into a new set of challenges as they have to balance their duties in their guild with preparing for a new life.
One possible plot development could be that Laxus initially struggles with the news. He might be worried about his ability to be a good father. However, as time passes, he realizes his love for Lucy and their unborn child and starts to prepare for the new addition to their lives. For example, he could start training harder to be a protector of his family.
Well, perhaps the story could start with a powerful magic spell gone wrong that turns Laxus into a baby. His friends might be shocked at first. They then have to take care of him, like feeding him and changing his diapers. It could be a really comical situation with his big, tough personality now trapped in a baby's body.
Well, it could be that Lucy and Laxus are on a mission together. As they face various obstacles, they grow closer. Maybe Lucy gets injured while protecting Laxus, and in a moment of relief and gratitude, Laxus kisses her. After that, they have to deal with the reactions of their guild mates. Some might be happy for them, while others might be a bit skeptical or jealous. Their relationship then develops as they navigate through these reactions and their own new - found feelings.
For Laxus, he might become more gentle and patient. Usually seen as a tough and somewhat brash character, having a baby could soften him. He would learn to control his temper better around the baby. For Lucy, she would likely become more confident in her maternal abilities. She has always been kind - hearted, but now she has to be strong for the baby. She might also develop new magical skills or ways to protect the baby.
One common theme could be family building. Since there's a 'baby' involved, it often explores how Laxus and Lucy adapt to becoming parents and building a family together. Another theme might be the growth of their relationship. Having a baby can put a strain or strengthen their bond, and this is often explored in such fanfiction.
Maybe it could be about Lucy's journey in raising the baby, like all the challenges she faces, from sleepless nights to learning how to feed the baby properly.
